Trait ImportSyntax 

pub trait ImportSyntax: Sync {
    // Required methods
    fn parse(&self, source: &str, tree: &Tree) -> ImportBlock;
    fn generate_line(&self, req: &ImportRequest<'_>) -> String;
    fn classify_group(&self, module_path: &str) -> ImportGroup;
}

Per-language import engine. One impl per supported language; syntax_for maps a LangId to its &'static dyn ImportSyntax. This is the single plug-in point that replaces the scattered match lang dispatch in parse_imports / generate_import_line_with_namespace / classify_group / is_supported. Adding a language is a new impl + one registry arm.

The existing engines are thin wrappers over the free functions they already used, so routing through the trait is behavior-preserving (golden-gated).

Required Methods

fn parse(&self, source: &str, tree: &Tree) -> ImportBlock

Parse all imports from a file’s already-parsed tree.

fn generate_line(&self, req: &ImportRequest<'_>) -> String

Generate a single import line from a structured ImportRequest. Engines read only the fields they support and ignore the rest.

fn classify_group(&self, module_path: &str) -> ImportGroup

Classify a module path into stdlib / external / internal.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
